SPECIFICATION forming part of Letters Patent No. 492,716, dated February28, 1893.

Application filed December 10, I891. Serial No. 414,615. (No model.)

To all whom, it may concern.-

Be it known that I, JOSEPH STANDRING DRONSFIELD, a subject of the Queenof Great Britain and Ireland, residing at the Atlas Works, Oldham, inthe county of Lancaster, England, have invented certain new and usefulImprovements in Fillet-Card Mounting Machines; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements upon a previous invention for whichI at present hold a patent in the United States of America, No. 244,568,dated July 19, 1881. The specification and drawings of the said priorpatent clearly show the general arrangement and method of mounting andactuating my fillet card mounting machine, and as machines of this typeare nowlargely used and well known in the United States, I do not in thepresent specification consider it nesessary to show more than thoseparts to which my improvements directly refer.

The nature of these improvements will be fully understood from adescription of the annexed two sheets of drawings.

On Sheet 1:Figure 1 is an end view of a fillet card mounting head. Fig.2 is a front elevation of the same. Fig. 3 is a sectional detail view ofpart of the presser through which the fillet passes to the tension cone.On Sheet 2:Fig. 4 is a plan of the fillet card mounting head.

In the improved head as herein described and illustrated, there arecertain parts which have been already described and illustrated in mysaid former specification, and certain parts which are new and forminter alia the subject matter of my present application. For example therevolving cone a the shunting plate I) and the presser trough c are allset forth in my former specification. With this proviso I will nowdescribe the apparatus.

The revolving cone a is supported in bearings in the sides of the head01 so as to revolve loosely therein. The step 1 of the largest diameteris covered with leather so that there shall be non-slipping contact withthe card fillet as it passes around with the said step.

The other two steps 2 and 3 are turned and smoothed so that the filletmay slip as it is taken around by the cone. The object of this will beexplained hereinafter. To the sides of the head and extending across infront of the cone a I bolt the shunting plate I) the function of whichis to divert the fillet from one step of the cone to the other as iswell understood. The shunting plate is formed at the end which isnearest to the step 3 with a sole to support the guide trough 0 throughwhich the fillet passes to the cone. Under my former patent I putpressure upon the cover 6 of the trough by a weighted lever, but undermy present improvements I use an adjusting screw f which passes throughan arm 9 pivoted at g to a bracket 9 which is secured to the side of thetrough. As seen by the plan view Fig. 4 a stop g limits the movement ofthe arm g. The foot of the screw f presses upon a plug h which occupiesa hollow boss 6' or the back of the cover. A buffer e of vulcanizedrubber is put beneath the plug h and thus makes the pressure upon thefillet of an elastic nature. The covercan easily be removed byretracting the screw f, and then swinging the arm to one side. The shaft2 carrying the cone a, projects through one of the bearings and carriesa brake pulley 7 which is embraced by a split brake strap j which isconnected by the stud to the side of the head. Au adjusting bolt Zpasses.

through the lugs of the split brake strap j for adjusting the strap toany required frictional drag. A coiled spring Z between the lugs keepsthe split strap apart against the pinch of the bolt Z. Thus I can effectany required resistance to the rotation of the cone a.

I now come to the tension indicating part of the apparatus. This ismounted at the letting off end of the head and consists of a pulley mhaving a curved periphery as shown so as to equalize the strain over thebreadth of the fillet. The pulley m is mounted in a jaw bracket to whichis pivoted by a stump o to a carrier p which slides to and fro inbearings q q in a bracket supported from the side of the head as clearlyshown in Fig. 4. The front of the carrier 1) constitutes a face plate goagainst which the jaw 77. is pivoted and held by the bolt 7' whichprojects from the plate 19 and enters a radial slot in the tail of jaw nthereby permitting the jaw with its pulley m to be adjusted to anyrequired angle so as to lead off the fillet properly. The tail of thecarrier 13 is surrounded between the bearings q g by double coiledsprings s s or it might be by a single coiled spring. To the face plate19 of the carrier I attach a rack which meshes with a sector a which isformed at the butt end of a pivoted index finger e which plays over anindex 10, supported from the carrier bracket. The face of the index tois marked with figures representing degrees of tension from zero up tothe highest tension required. In Fig. 4 the finger is shown at zero. Thesprings s s tend always to press out the pulley m to the position shownat Fig. 4 and these springs are so made and adjusted as to offergraduated resistance tothe pushing inward of the pulley m and carrier.This resistance represents certain degrees of tension upon the filletpassing over the pulleym and this tension is indicated on the index bythe finger '0 since the pushingin of the pulley m and carriercorrespondingly moves the rack t which turns the quadrant and indexfinger. By adjusting the pressure on the cover of the trough or of thefriction strap and pulley or of both I can adjust the tension on thecard fillet to any required degree. The progress of the card filletthrough the apparatus is clearly indicated by thearrows in and theskewed dotted lines in Figs. 1, 2 and 4. The fillet passes, dentsupward, into the trough c and beneath the presser cover 6. On leavingthe back end of the trough the fillet passes partly around the step 3 ofthe cone a. At the front of the cone it leaves the step 3 and passes tothe first shunting surface of the shunting plate I) by which it isdiverted to the next step 2 of the cone. The succeeding shunting surfacetransfers it to the last step 1 of the cone a which as has been said iscovered with leather. From this last step the fillet is diverted by thelast shunting surface to the pulley an over which it passes to be coiledupon .the cylinder being clothed.

In Fig. l the fillet 00 is seen entering the trough the dotted line asshowing its final exit to the cylinder. In Fig. 2 the strongly markedskewed dotted lines 00 mark the progress of the fillet through theapparatus. Asit passes around the back part of the cone a the conerevolves with it. Steps 2 and 3 of the cone being smooth there is lessfrictional grip between the fillet and these steps than is the case withstep 1 which being covered with leather has a greater frictional gripuponthe fillet. The surface speed of step 1 being greater than thesurface speeds of steps 2 and 3 the consequence is that the fillet isdrawn round and over the steps 2 and 3 at a speed slightly greater thantheir surface speeds'so that the fillet keeps slipping round faster thanthe steps 2 and 3 rotate. The result is that the cone becomes astretching or extending agent progressive in its action upon the filletfrom the least step 1 to the greatest step 3. On leaving the step 1 ofthe cone or the fillet is diverted by the last shunting surface of theshunting plate I) to the pulley m from whence it passes to be coiledupon the cylinder being clothed. As the fillet passes over the pulley mit is subjected to tension by the united influences of the trough c,brake pulley and strap t'j, pulley a and shunt plate 1). Such tensionacting as a resisting force to the ceiling on pull of the cylinder beingclothed, causes the carrier of the pulley m to yield inward againsttheresistanee of the graduated springs s s and thereby moves the indexfinger r so as to indicate the degree of tension on the index to. Toattain any required degree of tension it is only necessary to regulatethe pressure of the cover in the trough 0 upon the fillet or the brakingeffect of the pulley and split strap 2 j by means of the respectivescrews.

A noticeable feature of my apparatus is that I obtain the requisitetension upon the fillet gradually throughout the length of the portionin the apparatus bythe united effects of the trough, the brake strap theshunting plate and the stepped cone. The curved periphery of the rollerm puts the greatest strain upon that part of the fillet most capable ofresisting it, viz the center, and a lesser strain upon the edges whichare not so strong.

The (letter or carding cylinder upon which the fillet is guided andwound by the mounting machine just described does not appear in thedrawings as I do not consider it requisite to show it. Its positionrelatively to the mounting head is moreover shown clearly in thedrawings attached to the specification of my aforesaid prior UnitedStates Patent.
